PPTX Pie and Bar Charts title not visible


I am trying to display a presentation built on Microsoft Office PPTX in LibreOffice. The actual presentation have a pie chart with a title on it, as this:

However, when I try to open the same file in LibreOffice, I don’t get the title and the chart gets bigger:

The same issue occurrs also with the bar charts. I am planning using LibreOffice programmatically, but this problem is a huge blocker now. I would be glad if you can suggest any solution, which may also include changing something in the original PPTX file as well. Thanks a lot.
